Operation

Changing Configuration Options

The DSU/CSU is an intelligent device that displays only valid options for the current configuration. Therefore, you are only presented with menu choices that are consistent with the current configuration and operational state of the DSU/CSU; invalid combinations of configuration options do not appear. For example, if the DTE Drop/Insert (DSX-1) interface selection is disabled, many of the menu choices do not appear.

The DSU/CSU offers configuration options located in the following memory areas:

HCurrent. This is the configuration option set currently active for the DSU/CSU is stored here. Before a configuration option set becomes active for the DSU/CSU, you must save the set to the Current area. When the DSU/CSU is shipped from the factory, the Current configuration option set is identical to the Default Factory set. This area can be written to and controls the current operation of the device.

HCustomer 1. This is the first of two sets of customer-defined configuration options. This area can be written to.

HCustomer 2. This is the second of two sets of customer-defined configuration options. This area can be written to.

HDefault Factory 1. This is a set of configuration options preset at the factory. This set is determined by what is considered to be the most common configuration used in the DSU/CSU market. Default Factory 1 options are read-only.

HDefault Factory 2. This is a set of configuration options preset at the factory. This set is determined by what is considered to be the second most common configuration used in the DSU/CSU market. Default Factory 2 options are read-only.

The configuration options are divided into functional groups. Appendix C,

Configuration Options, contains a list of the configuration options and defaults.

The DSU/CSU arrives with two preset factory default configuration settings.

These settings are based on the following:

HDefault Factory 1 – ESF framing format with B8ZS line coding format for both the network and the DTE Drop/Insert (DSX-1) interfaces. Data ports are unassigned.

HDefault Factory 2 – D4 framing format with AMI line coding format for both the network and the DTE Drop/Insert (DSX-1) interfaces. Data ports are unassigned.

If neither of the factory default settings support your network’s configuration, you can customize the configuration options to better suit your application.

Use the Configuration branch of the menu tree to display or change DSU/CSU configuration options (see Appendix C, Configuration Options).
